The selection in a TableView takes an incredible long time.
In Swing, the selection occurs almost instantly.
Example Code:
http://pastebin.com/A0hpTxjh
Steps to reproduce:
1. Compile and run example, a TableView with 8 columns and 10.000 rows will appear
2. Select the first cell (column "Data 0")
3. Scroll to the bottom of the table
4. Press shift and select the last cell (column "Data 7")
5. UI will block for a long time
When selecting only 1.000 rows, for me the UI blocks ~80ms which is also too much in my opinion. When implementing a custom mouse selection, the delay is noticeable even with a very small amount of data.
